Introduction
Object Oriented Programming in any language is the use of objects to represent functional parts of an application and real life entities. For example you may have a Person object to hold the data related to a person and even provide some functionality that this person may be capable of.
Object Oriented Programming has long been used in games to represent the objects such as a User or an Enemy, or even a Weapon. This amazing way of programming has proven just as useful in software and web development.
In my opinion any OOP language should have:
* Abstract data types and information hiding
* Inheritance
* Polymorphism
This can all be done using PHP classes:
|
|
<?php
class Something {
// In OOP classes are usually named starting with a cap letter.
var $x;
function setX($v) {
// Methods start in lowercase then use lowercase to separate
// words in the method name example getValueOfArea()
$this->x=$v;
}
function getX() {
return $this->x;
}
}
?>

Of course you can use your own nomenclature but having a standardized one is useful.
